It is not safe to place babies on their sides or stomachs to sleep, not even for a nap. The safest sleep position is on the back. Babies who sleep on their backs are at lower risk for SIDS than babies who sleep on their stomachs or sides.
Pregnancy risk factors
Mothers who have inadequate prenatal care. Abnormal placenta. Low weight gain during pregnancy. Maternal age under 20 years old.
Some individuals affected by SIDS may benefit from counseling or psychotherapy to cope with the loss of the infant. This may include support from a social worker, psychologist, nurse, psychiatrist or other health professional, either in a group or one-on-one setting.
More than 90% of SIDS incidences occur before six months of age. “SIDS is rare and devastating, but encouraging parents to put their children to sleep on their backs drastically helped reduce unexplained infant deaths,” says Northwestern Medicine Pediatrician Michael D. Bauer, MD.
While the cause of SIDS is unknown, many clinicians and researchers believe that SIDS is associated with problems in the ability of the baby to arouse from sleep, to detect low levels of oxygen, or a buildup of carbon dioxide in the blood. When babies sleep face down, they may re-breathe exhaled carbon dioxide.
Sleeping position: Sleeping on the stomach is a major risk factor for SIDS.
Most SIDS deaths happen in babies between 1 and 4 months old, and cases rise during cold weather. Babies might have a higher risk of SIDS if: their mother smoked, drank, or used drugs during pregnancy and after birth. their mother had poor prenatal care.
The rate of SIDS deaths per 100,000 live births has declined in Australia since the beginning of national public education campaigns about risk factors associated with SIDS in 1991 (AIHW 2012). Between 2007 and 2017 the rate declined from 28 per 100,000 to 6 in 2017, following a peak in 2009 of 32 per 100,000.
It may be because babies don't sleep as deeply when they have a pacifier, which helps wake them up if they're having trouble breathing. A pacifier also keeps the tongue forward in the mouth, so it can't block the airway.
Even though the thought can be deeply unsettling, experts agree that there aren't any warning signs for SIDS. And since SIDS isn't diagnosed until after an infant has died and the death has been investigated, you can't catch SIDS while it's happening and stop it, for instance, by performing CPR.
The potential factors that contribute to the occurrence of SIDS include inadequate prenatal care, low birth weight (<2499gr), premature infants, intrauterine growth delay, short interval between pregnancies and maternal substance use (tobacco, alcohol, opiates).
Some studies have shown an increased risk of SIDS and unintentional suffocation when babies are swaddled if they are placed on their stomach to sleep, or if they roll onto their stomach. If babies are swaddled, they should be placed only on their back and monitored so they don't roll over.
Infants at the age when SIDS occurs quite frequently spend most of their sleep in a stage known as rapid eye movement or REM sleep. This sleep stage is characterized by the dysregulation of various mechanosensory airway and chemosensory autonomous reflexes that are critical for survival (18, 19).
Babies who usually sleep on their backs but who are then placed to sleep on their stomachs, such as for a nap, are at very high risk for SIDS. Sleep in an adult bed with parents, other children, or pets; this situation is especially dangerous if: The adult smokes, has recently had alcohol, or is tired.
Although infants at high risk for SIDS cannot be identified early, several maternal, neonatal, and postneonatal factors associated with such increased risk have been identified (8). Parents and health-care providers should be aware of the increased risk for SIDS during the winter season in the United States.
After 6-months old, babies are typically able to lift their heads, roll over, or wake up more easily, and the risk of SIDS decreases dramatically. However, 10% of SIDS happens between 6 and 12 months of age and safe sleep recommendations should be followed up to a baby first birthday.
White noise reduces the risk of SIDS.
We DO know that white noise reduces active sleep (which is the sleep state where SIDS is most likely to occur).
Goodstein said, when babies sleep in the same room as their parents, the background sounds or stirrings prevent very deep sleep and that helps keeps the babies safe. Room sharing also makes breast-feeding easier, which is protective against SIDS.
SIDS is most common at 2-4 months of age when the cardiorespiratory system of all infants is in rapid transition and therefore unstable. So, all infants in this age range are at risk for dysfunction of neurological control of breathing.
Dr. Hauck: We don't know for sure why room-sharing without bed-sharing is protective, but we have some theories. One is that the babies are sleeping more lightly because there is more movement around them (so they cannot get into as deep a sleep, which can contribute to the final pathway in SIDS).
Babies who are breastfed or are fed expressed breastmilk are at lower risk for SIDS compared with babies who were never fed breastmilk. According to research, the longer you exclusively breastfeed your baby (meaning not supplementing with formula or solid food), the lower his or her risk of SIDS.
He should sleep in his own crib or bassinet (or in a co-sleeper safely attached to the bed), but shouldn't be in his own room until he is at least 6 months, better 12 months. This is because studies have shown that when babies are close by, it can help reduce the risk of Sudden Infant Death Syndrome, or SIDS.
